[Classes 72 and 82 (i)] [Also in Group XXII] Permanent magnets are hot forged from cast alloys containing 5-9.5 per cent. of aluminium, 1-3 per cent. of titanium, 20-30 per cent. of nickel and the balance iron, with or without up to 1 per cent. of copper vanadium, niobium, tantalum, chromium, molybdenum, tungsten, cobalt and manganese, up to 0.1 per cent. of calcium, barium, or strontium; and less than 0.2 per cent. of carbon. Boron, lead, arsenic, antimony, bismuth, sulphur, selenium, tellurium, silver, tin, and phosphorus should be absent or low. In making the alloy, the titanium may be added as an alloy consisting of 4 per cent. of titanium, 15 per cent. of aluminium, 20 per cent. of nickel, 10 per cent. of manganese, and the balance chiefly iron. The alloys may be softened for machining by heating to over 1200‹F., e.g. 1500-1800‹F., and cooling slowly, or by finishing the hot-working within that range and cooling slowly. The magnetic properties may be restored by heating to 2000-2400‹F., cooling to below 1400‹F. or quenching, and holding at 1000-1400‹F. for “-24 hours.

The signals TB1, TB2 are applied to a logic circuit, as shown, which also receives gating signal G1 and G2 at times t4 and t5 respectively, and a signal TE indicative of the expected output signal from the logic unit under test, and which produces a result signal TR, from a latch 17. The operation of the complete circuit is summarized by the following table: The result signal TR is recorded at times t4 and t5 and correlated with the expected signal TE. A plurality of circuits are tested and the results evaluated under the control of a computer. A circuit employing known semi-conductor modules Fig.2a (not shown) is described for producing two-level signals for application to a circuit under test. The circuit incorporates a bi-stable circuit whose condition can be changed whenever a sync pulse is applied, and whose state determines the level of the output signal.

Abstract: 711,248. Type-bar-making machines. MERGENTHALER LINOTYPE CO. March 5, 1952 [March 9, 1951], No. 5759/52. Class 100 (3) Assembling-apparatus-; magazines.-A typographical composing machine such as known under the Registered Trade Mark "Linotype" comprises an assembling mechanism mounted on a hinged frame for movement from and to its operative position, a lock to hold the frame in its operative position, and a safety device to prevent the release of the lock when the assembler elevator is in its composing position. In a machine of the general construction described in Specification 706,438, the assembling mechanism is mounted on a frame 13, Fig. 1, hinged at 14. The frame 13 is locked in operative position by means of a pawl 15, Fig. 2, mounted on a shaft 16 and engaging in a slot in a block mounted on the frame 13. The pawl 15 is released by rotating the shaft 16 by means of a handle 17. Rotating of the shaft causes movement of a latch 22 about its pivot 22a, by means of an eccentric on the shaft engaging an elliptical hole in the latch. If the elevator B is in composing position, the nose of the latch 22 abuts it and prevents release of the pawl 15 until the elevator has risen sufficiently to allow the frame to be swung open without the line resistant finger 8 fouling the elevator. When the pawl 15 is released, the latch 22 prevents descent of the elevator until it is again locked. Matrices lodged in the magazine exit are detected by a feeler bar 25, Fig. 9, operated by a handle 26, the operation of which rotates a shaft 27 carrying at each end a crank arm 28 to actuate the bar through levers 29 and slides 25a. One of the arms 28 has a cut away portion 28a. The shaft 16 has an extension 16a carrying a disc 30 with an arcuate portion 30a and straight edge 30b. In the normal position of the arm 28, the edge 30b abuts the arm 28 and prevents rotation of the shaft 16 and release of the pawl 15. When the bar 25 is operated, the cut away portion 28a receives the arcuate portion 30a to allow release of the lock and the arcuate portion 30a then prevents retraction of the feeler bar until the frame 13 is again locked.

An internally cooled mandrel 14 for a tube extrusion press has a longitudinal passage 26 terminating at the forward end of the mandrel in an opening 36 normally closed by a valve 42 but which is opened upon substantial elongation of the mandrel. A coolant liquid such as water is supplied to a tube 28 having spaced ports 30 through which the liquid enters the mandrel passage 26. The forward end of tube 28 carries a plug valve 42 which enters opening 36. The mandrel is used initially to pierce a heated billet B which is then extruded into a tube by a ram 22 and press disc 16. If considerable elongation of the mandrel occurs during extrusion, such as may lead to ultimate fracture, Fig. 3 (not shown), the valve 42 opens to permit escape of coolant. In another embodiment, Fig. 4 (not shown), the valve consists of a rubber or like washer on the end of tube 28.
